CARGO HOOK.

Application filed February 26, 1923.

To all 10. mm it may concern:

Be it known that I, Louis Cor, subject of Spain, and resident of 50 VSackett Street, Brooklyn, in the county of Kings and State of New York,have invented certain new and useful Improvements in Cargo Hooks, ofwhich the following is a specification.

This invention relates to hooks in general, and particularly to the kindemployed for suspending cargo from derricks or other hoistingimplements.

The main objects of the present invention is to provide a simpleinexpensive and safe device, by means of which a load may be eithertransferred from one hoisting device to another or from a hoistingdevice to a place of repose and permitting therelease of the load byrelaxing the cable by which the load is suspended and by reversing theposition of my device; I

In order to better understand the working principle of my. device, it isnecessary to refer to the similar device now in use and consistingmainly of gripping claws or U shaped hooks, which are adapted to suspenda load, and manually operable releasing means by way of which thesuspension hooks may be opened, thus permitting the load to drop. Thegreater the load the harder it becomes to release such devices. Usuallya line is attached to the release and the helper is to pull thereonuntil the device is opened. 7

Moreover most of the releasing devices keep the hooks closed only aslong as the load is suspended from the latter, but in the event that theload would be transferred to another hoisting device it is hard tooperate the release.

From the foregoing it will be evident that such devices are not onlyimpractical but even dangerous in operation. My invention is designed toovercome the aforementioned disadvantage by employing an entirely newprinciple of operation.

The advantages of my device will be more fully apparent from thefollowing description and accompanying drawings, forming part of thisspecification, but representing only one of the many possibleembodiments of my device, and in which:

Figure 1 is the side elevation of my device partially in section, inclosed position while suspending a load.

Figure 2 is a side elevation of my device Serial No. 621,346.

partially in section and showing it reversed in open condition.

Figure 3 is a partial end view seen from lines 33 of Figure 1.

Referring to the drawings numeral denotes the load suspension member.which is generally of a dog-like shape and provided with a depression 11between. fingers 12 and 13.

Finger 12'is reduced at it upper portion as indicated at 14. The lowerend of member 10 has a reduced extension 15, provided with an eye 16,which passes a pin 17 forming a hinged connection with locking memberlS.Locking member-18 is provided with a T-shaped gravity head 19 having aflute-like recess 20, adapted to register with the reduced extension 14of the load suspension member 10. At the outer end of the head there areprovided one or more guide apertures 21 and 22 the purpose of which willbe explained later.

The leg 23 of the locking. member 18 is also'perforated at 24 and 25. Atthe lower end of the leg 23 there is provided a recess 26, in whichfreely swings extension of load suspension member 10. At the extreme endof leg 23 there is provided a rest or stop 27, which limits the outswingof member 10.

Finger 13 of member 10 provides a stop for the latter when bearingagainst leg 23 of member 18. Below finger 13 there maybe provided an eyeor hook indicated at 28, for receiving a single flexible element i11-dicated at 29 and which is adapted to close and keep the two members inclosed position when desired, but permitting an opening of the memberswhen it is necessary. When such single flexible element 29 is employedit passes through aperture 2 1 of leg 23 and through aperture 2110 head19. Instead of the single flexible member 29 there might be employed adouble flexible element 30, in which case a fastening lug 31 provided inthe body of member 10, is employed for attaching flexible element 30. Inthis case flexible element 30 passes through apertures 21 of the head 19and 24 and of the leg 23, and back through aperture 22 of head 19.However, any other suitable arrangement of fastening the flexibleelement may be employed.

In Figure 1 my device is shown in closed position and suspended by meansof flexible element29 and supporting a load indicated i r by the brokenlines I. v

Assiimethat my device is now attached to a crane and the load I is heldby convenient means Within hook-shaped depression, 11. Now the load maybe transferred from one place to the other \VltllOLlt difiiculty and;

with absolute safety.

When now the suspension means-support ing the load is engaged by anotherhoisting device and pulled up in the direction shown in Fi ure 2 bvbroken lines II while at the same time flexible element 29 isSlaekr-ned,

my device will be turned :to the 1)0Sli'l()1-1 ll1- dicated-in Figure 2.In this position the gravity head 19 drops down and disengages finger12' of member 10, thereby opening; my ,deviceand releasing thesuspension means of the load and permitting'the latter to be. now freelysusprmded=by the other hoistlng device.

The same manner O'E'OIJQl'fltlOIl applies for instance, in the casewhere cargo is to belifted into the hull oil a ship, withthe exceptionthat a second hoisting device-is not employed, but instead a helperpulls the sling suspending the cargo to one I side-untilthe reversal ofmy device has taken place and member 10 released. 7
